mountd can now monitor clients appearing and disappearing in /proc/fs/nfsd/clients, and will log these events, in liu of the logging of mount/unmount events for NFSv3. Currently it cannot distinguish between unconfirmed clients (which might be transient and totally uninteresting) and confirmed clients. So add a "status: " line to the "info" file which reports either "confirmed" or "unconfirmed".
